Abstract

La présente invention concerne un procédé et appareil de commande d'une source de rayonnement modulée (qui peut être, par exemple, une source de lumière infrarouge). Le procédé affecte la puissance commandant une source lumineuse de telle manière à minimiser le temps de chauffage de la source. L'appareil permet la commande à rétroaction d'une source lumineuse selon des puissances ou températures spécifiées. Les modes de réalisation divulgués peuvent améliorer les prestations et la longévité de la source et réduire les coûts opérationnels de la source.
